In a network, ________ is used to logically segment a LAN into different broadcast domains.
- Gateway
- Router
- Subnetting
- VLAN
VLAN (Virtual Local Area Network) is used to logically segment a LAN into different broadcast domains.
In a network with multiple gateways, _______ can be used to allow automatic failover and load balancing.
- HSRP (Hot Standby Router Protocol)
- OSPF (Open Shortest Path First)
- VRRP (Virtual Router Redundancy Protocol)
- ARP (Address Resolution Protocol)
In a network with multiple gateways, VRRP (Virtual Router Redundancy Protocol) can be used to allow automatic failover and load balancing.
PPP's ability to support multiple protocols simultaneously is achieved through the ________ protocol.
- LCP (Link Control Protocol)
- NCP (Network Control Protocol)
- IPCP (Internet Protocol Control Protocol)
- HDLC (High-Level Data Link Control)
PPP's ability to support multiple protocols simultaneously is achieved through the Network Control Protocol (NCP). NCP is responsible for negotiating and configuring different network layer protocols.
The process of combining multiple VLANs into a single broadcast domain over a trunk link is known as VLAN ______.
- Aggregation
- Merging
- Tagging
- Translation
The process of combining multiple VLANs into a single broadcast domain over a trunk link is known as VLAN Aggregation.
An IT manager is tasked with upgrading the network cabling in a hospital to support advanced medical imaging equipment and ensure patient data privacy. What cable characteristics should be considered?
- Cat 5e
- Cat 6
- Fiber Optic
- Shielded Twisted Pair (STP)
Fiber optic cables are suitable for high-speed transmission and are ideal for supporting advanced medical imaging equipment while ensuring data privacy in a hospital setting.
Which type of firewall uses a defined set of rules to decide whether to allow or block network traffic?
- Proxy firewall
- Stateful firewall
- Stateless firewall
- Application-layer firewall
A stateful firewall uses a defined set of rules to decide whether to allow or block network traffic based on the state of connections.
In a network, _______ is used to connect segments of a LAN and contains logic to filter traffic based on MAC addresses.
- Hub
- Repeater
- Router
- Switch
In a network, a Switch is used to connect segments of a LAN and contains logic to filter traffic based on MAC addresses.
What is a key disadvantage of using a star topology in very large networks?
- Complex Wiring
- High Maintenance Cost
- Limited Scalability
- Single Point of Failure
A key disadvantage of using a star topology in very large networks is limited scalability. As more devices are added, the central hub may become a bottleneck for data traffic.
Which protocol within IPSec is used to provide data integrity and authentication?
- AH (Authentication Header)
- ESP (Encapsulating Security Payload)
- IKE (Internet Key Exchange)
- SSL (Secure Sockets Layer)
The Authentication Header (AH) protocol within IPSec is used to provide data integrity and authentication.
Which system is utilized for sending and storing log messages in a network, helping in network management and security?
- DHCP
- DNS
- Syslog
- HTTP
Syslog is a system used for sending and storing log messages in a network, aiding in network management and security.
In DHCP, what mechanism is used to ensure that multiple DHCP servers do not offer conflicting IP addresses?
- DHCP Snooping
- DHCP Relay
- DHCP Failover
- DHCP Lease Renewal
DHCP Failover is used to ensure that multiple DHCP servers coordinate and do not offer conflicting IP addresses to clients, enhancing network reliability.
Which feature in switch configuration allows for assigning multiple ports to a single broadcast domain?
- Port mirroring
- STP
- Trunking
- VLAN
Virtual LANs (VLANs) in switch configuration allow for assigning multiple ports to a single broadcast domain, improving network segmentation and management.
